Armasight (FLIR) Helios 640 3-24x75 (60Hz)

The HELIOS 640 3-24X75 (60HZ) is a thermal imaging bi-ocular made by Armasight (FLIR) and is part of the Helios series. It utilizes a 640 x 512 pixels thermal core with a refresh rate of 60Hz and features a 75mm lens, giving you a field of view of 8.3 x 6.6 degrees.

The Helios is a solid state, uncooled, long-wave infrared, magnified, dedicated handheld thermal imager intended for day and nighttime missions. The 24/7 mission capability is just one of the many strengths this product line has to offer. Thermal imaging technology also allows you to detect targets by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants.

Unlike the use of laser targeting or near-infrared illumination to augment night vision equipment, Helios thermal imagers are extremely difficult to detect with other devices, as they emit no visible light or RF energy. Armasight is convinced that the Helios thermal imaging bi-ocular represents one of the most sophisticated devices on the market today, due to its superior price-to-performance value.
